Abstract (en)

[origin: EP2247094A1] An orthophotographic image creating method and an imaging device both mainly for creating a topographic map or for using an orthophotographic image as a photographic diagram. The method enables relatively easy imaging and creates an orthophotographic image with an excellent quality. The imaging device is suitable for imaging using such a method. A target area (1) is imaged dividedly from a platform such as an airplane while the angle of depression and the focal lengths (f, f) with reference to a predetermined ground resolution are being varied. An altitude model (5) of the whole target area (1) is made according to the matching between the imaged superposed parts (4) of the altitude models (3, 3) made according to dividedly-captured images (2). Using the altitude information about the altitude model (5), each dividedly-captured image (2) is subjected to orthographic conversion so as to create an orthophotographic image of the whole target area.
